Gunsmithing Crater on Rem 700 AAC-SD Bolt Primer Impact Area

[cperazza]

Found a crack/crater on my Rem 700 bolt around the firing pin area outlining were the primer/case impacts. I reload 175 gr Nosler/Barnes N150 (43.5 gr), OAL 2.92", case trim 2.011". Is this a manufacturing defect? What is causing this? Is the rifle safe to fire like this? Any help is appreciated.

Crater from gas leakage from run'n to hot of a load.
Your OK, at this point-back the load off--

^^^ Yep. Time to slow the hot rod load down a bit. You are at the top of their load data.

Stop shooting those rounds. That bolt face damage appears to be caused by excessive pressure. You load data is a max. load per VihtaVuori but would probably be O.K. in a factory Remington chamber if you were not jamming your bullets. If you want to go faster use a different powder and don't jam. If you are using N150 because thats all you have on hand reduce your COAL to 2.80" and take 5% of your load weight out and you will be safe if slow. Your bolt face may is repairable, find a good gunsmith. Good luck.
